| Outline of Final Research Achievements |
The thermal conductivity of main-chain liquid crystal PB-10 polyester hardly depends on the lamellar size although the thermal conductivity was measured for non-oriented (bulk) samples.
The thermal conductivity of BB-n polyesters ranged from 0.3 - 0.4 Wm^-1K^-1 and higher for even-member BB-n than off-memeber ones. Even-member BB-n polyesters are crystalline, so the thermal conductivity may be affected by the crystallinity.
PmBEn polymers form two types of smectic LCs that differ in their degree of side-chain overlap, which affects the thermal diffusivity. Smectic A1 (SmA1) LCs with fully interdigitated side chains have 20% greater thermal diffusivity than smectic Ad LCs with side chains overlapping at the alkyl tail. The variations in thermal diffusivity in PmBEn polymers are correlated with the smectic LC structures characteristic of side-chain LC polymers.
